I think it's best explained as though you are going with a big, extended family. You won't spend all day together, but you'll want to all be on one photopass account, and get one CD (or two or three, however many CDs to hold as many pictures as there are).
So you and your immediate family will get a card and will have pictures taken and "put" on that card. Your aunt and her family will have their own card. Your cousins from the weird side of the family will have their card. And so on.
At the end of the trip, everyone would give their cards, or their card numbers, to one person, who would then put all those card numbers onto one account. Everyone would then be given the email and password combo so that they can edit their own pictures. Crop, delete the awful ones, add borders... Once everyone is done, the person in charge of the account would order the CD.
If it's a close knit family, maybe they would just be in charge of that CD, and make prints and send them out. But if it's a widespread family, like mine, and if you're like me, you could read the license as being allowed to make copies of the CD, still for personal use, so that each main family can have a CD, to them make prints from, again, for personal use.
So if you imagine that you're not talking about a bio or adopted family, but rather a family of people from the Dis, you can see how a Share works!
There's a lot of trust involved, and just like with those weird cousins I mentioned above you might end up with someone who messes things up.
I participated in a Share that worked nicely on this forum. I then saw the beauty of photopass, of having that CD and holding the license to those pictures forever, and I decided that it's worth paying full price for. HOWEVER I like an in-between that I noticed...where everyone goes in on the main price, and then you order enough copies directly from photopass (at $20 each, 'cuz, you know, it costs $20 for the extra CD and the time to copy the pictures, LOL) for each family in the Share...that way everyone has their own license, their own "pretty" CD and case, and it's hard to argue about that (though I'm sure people still would, outside the nice
disneyland forum).
Hope that helps!

With DL/DCA photopass, you can ask the photographers outside the castle to "put" tinkerbell in your hand, and the DCA photogs near ToT and even near the entryway can "put" Stitch coming out of the ground. And if your pix end up like mine, and Stitch didn't actually come through (it's something they do with their cameras), the photopass people that you contact by email can help to put him in. I imagine they could help with Tink, too, but I didn't have that picture done.
